' CARBURET'OR ATTACHMENT FOR EXPLOSIVE ENGINES.

Application filed November 13, 1920. Serial No. 423,951.

To all whom it may concern.

Be it known that I, Jnssn G. HILTON, a citizen of the United States,residing at Mena, in the county of Polk and State of Arkansas, haveinvented a new and useful Carburetor Attachment for Explosive Engines,of which the following is a specification.

This invention relates to an attachment for carburetors used inconnection with explosive engines, one of the objects of the inventionbeing to provide a device which can be readily placed in positionbetween the carburetor and the intake manifold of an engine and whichserves to direct heated fresh air either with or without steam into theintake manifold where it will mix with the gas delivered from thecarburetor, it being possible by means of this attachment, to eifect aconsiderable saving of gas after the engine has once been started, thevarious parts of the attachment being controlled easily by the driver.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a side elevation of a portion of a vehicleand engine having the present improvements combined therewith.

Figure 2 is an enlarged side elevation of the attachment.

Figure 3 is a section on line 3-3, Figure 2.

Figure 4 is a top plan view of a portion of the attachment.

Referring to the figures by characters of reference A. designates aportion of an engine having an intake manifold B and an exhaust manifoldC, there being a carburetor D mounted in the usual way and from whichprojects the stem E of the throttle valve.

The attachment constituting the present invention includes a hollowmetal gasket 1 adapted to be placed between the flange b of the intakemanifold B and flange d of the outlet end of the carburetor, said gasketand the flanges being held together by bolts 2 which are extendedthrough them as shown. The gasket 1 is hollow and has a tubular stem .3projecting upwardly therefrom, there being contained within the upperportion of the stem a valve 4 the stem 5 of which has an angle lever 6at one end. A spring 7 connects one arm of this lever to the lowerportion of the gasket while the other arm of the lever has an operatingrod 8 attached thereto and extending rearwardly to a point where it canbe reached and actuated readily by the driver. Another valve 9 ismounted in the lower portion of the stem and the stem 10 of this valveis provided with a lever 11 coupled, by an arm 12, to the stem E of thebutterfly valve in the carburetor. The arm 12 is designed to swingduring the rotation of the stem E and will at that time actuate thelever 11 and valve 9 so as to open or close the valve to maintain aproper proportion of air and gas Within the intake manifold.

The upper end of the tubular stem 3 is seated within an opening 13formed in the bottom of a plate 14 which is suitably fastened to theexhaust manifold and has an air passage 15 extending from the opening 13upwardly through the top of the plate and close to the exhaust manifoldC. An ear 16 projects upwardly from the plate and has an opening 17 inwhich is secured one end of a pipe 18. This pipe is coiled about theexhaust pipe 0 of the engine and is adapted to receive water from acontainer 19 mounted at any desired point above said pipe. A regulatingplate 20 is mounted on the upper end of the plate 14; and is adapted topartly cover the intake end of the passage 15, said plate being slottedas at 21 and engaged by a holding screw 22.

While the engine is being started the valve 4 can be closed so that arich mixture will flow through the carburetor to the engine. After theengine has started and the exhaust manifold has been heated, the valve 1can be opened by pulling on the rod 8 and securing said rod in anysuitable manner. Thus fresh air heated in its passage across the exhaustmanifold will be sucked through the passage 15 and through the stem 3into the gasket 1 where it will mix with the gas flowing from thecarburetor to the intake manifold. This heated air will enable a reducedquantity of gas to be used, this quantity being first determined by theproper adjustment of the plate 20. At times moisture may be supplied tothe mixture by directing water from the container 19 through the pipe18. This pipe, being wrapped about the pipe 0 will be heated to a hightemperature, thus producing vapor or steam which will be dischargedacross the open upper end of the passage 15. It will here be sucked intothe passage together with the heated air and the steamand air thoroughlymixed with the gas as it passes through the gasket 1.

It is to be understood that the attachment may be made in various stylesfor use in connection with different kinds of cars, the constructionillustrated being designed pridnarily for use in connection withthe wellknown Ford engine. 7

As shown in Figure 1 a suitable needle valve 23 or the like can be usedfor controlling the fiow of water from the container 19.

What is claimed is: In an attachment of the class described,

a hollow metal gasket insertable between the carburetor outlet and theintake inanifold of an engine and having a tubular stem extendingupwardly therefrom and provided with a valve, a spring connected to holdsaid valve normally in closed position, manually controlled means foropening said valve against the tension of said spring, a casting mountedon said stem and having an air inlet passage communicating with thestem, said casting being shaped to fit over the exhaust manifold andequipped at it supper end with a chamber provided with an adjustableclosure to control the entrance of air thereto, said casting havingmeans for directing a jet of steam across the opening controlled by saidclosure.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.

JESSE G. HILTON.
